Application filed May 20, 1922; Serial no. 562,367. j

T 0 aZZ whom it may concern Be it known that I, Lnwrs A. MoLoGNn, a citizen of the United States, residing at Smithton, in the county of Westinoreland and State of Pennsylvania, have invented certain new and useful Improvements in lVindow Locks, of which the following is a specification, reference being had to the accompanying drawings.

This, invention relates to window locks and has for its object to provide a device of this character capable of being applied to any type of window without marring the window by the use of screws or like fastening means.

Another object of the invention is to pro to support a member arranged. to engage both sashes to prevent movement of'said sashes in the usual manner beyond a certain point predetermined by the adjustment of the bracket on the sash.

WVith these and other objects in View, the

invention consists in the improved construe-- tion and arrangement of parts to be hereinafter more particularly described, fully claimed and illustrated in the accompanying drawings, in which Figure is a fragmentary longitudinal sectional view of a window frame showing the invention applied;

Figure 2 is a fragmentary top plan sectional view of the window casing showing the position of the lock on the rail of the window; p

Figure 3 is a perspective view of the bracket with the wedge member and fasten ing means removed; and

Figure 4 is a perspective view of the wedge member. 7

Referring to the drawings, 5 designates a bracket comprising arms 7 and 8, the arm 7 being stepped longitudinally thereof. The end portion 9 of thearm is adapted to engage a portion of the window, while the end portion 10 is provided with an elongated slot for the purpose of adjustment. The intermediateportion 11 of the arm 7 is provided with a bearing opening 12, the purpose of which will be hereinafter described.

The arm 8 of the bracket is. substantially l '-shaped, the end portion 18 of the arm havmg an elongated opening 14: adapted at times to register with the portions of the opening in the end portion 10 of the arm 7, a bolt 16 being passed through said registerngopenings'to hold said arms in their adusted positions. arm 5 1s provided with a bearing opening 18 adjacent the junction of the end portion 17 with the end portion 13, the opening 18 sub stantially registering with the opening 12' of the arm 7 for the reception of a bolt or shaft 19, the bolt being provided with a nut 20 to properly hold the bolt in accordance with the adjusted positions of the arms 7 and'8. The nut 20 of the bolt 19 may also be used toadjust the'arms 7 and 8, in view of the fact that when saidvnut is rotated in one direction'the arms 7 and 8 are moved toward each other as the head of the bolt en gages the intermediate portion 11 of the To permit a further range of adjustment a plate 2 1. is provided, said plate having its longitudinal edges 22 extended outwardly at right angles to the plate to provide guides between'which the end portion 17 of the arm 8 is slidable, one end portion of the plate 21 having an elongated opening 23 adapted to IBCGlVG the bolt 19 and also to register with the opening 18. The end portion 10 or intermediate portion 11 of the arm 7 substantially cooperates with the end portion 13 of the arm 8 to provide a compartment adapted to receive a wedge member 24, said wedge member having an opening adapted to receive the portion of the bolt disposed within the compartment. that the compartment provided in the arm may be adjusted according to the width of the ,rails of the sash. In the formation of the wedge member, the face 25 is beveled from a point inwardly of the upper end 26 of the wedge, the opposite face 27 of the wedge being straight. The purpose of this is to permit a proper locking action by causing a portion of the face 25 to engage the It is of-course obvious.

The'end portion 17 of the i window sashand at the same time permit the flat face 27 to engage the sash longitudinally of said face. "By this means the wedge memher is firmly lodgedxbetween the sashes. This arrangement also permits the wedge bracket 5 may be, positioned any point titting properly in lonp'itud-inall of the vertical rail oi the una w 1 a per sash and in engagement with toe inner tare oi said rail so-as, to position the point .otv the wedgetoward the lower sash. By

this means, upon movement ofthe upper sash, or vice versa, the extent of said movement will be limited, accoroing to the position ofthe bracket onthe rail of the upper sash. 'lhispermits the upper sash to be lowered certain distance and the lower sash to be raised a certain distance, for proper Ventilation, withoutdanger of either sash being moved to a posit-ion to permit entranee of a person or to permit the bracket to be reached by a person from the outside. l1"- it is not desired to use lock to hold the windows in position for ventilation, the bracketmay again be adjusted toward the lower rail of the upper sash so to provide a lock for holding both of said sashes in their closed positions, moven'ient of either sash being positively prevented.

From the foregoing it will be readily seen that this invention provides a novel form of .window. lock capable ottbeing applied to any windowsas 1 without thense of nails, screws or like fastening means, and also capable of being used in connection with windows r gardless of whether they {it the wind w casing or not, andreg'ardless oi the weather, asthe lock does not dependfon the windows the casing for its efficient operation, and all of these features are possessed by a device composed of only a small number oi simple parts.

l Vhat is claimed is r- A window lock comprising a pair of arms adjustably connected at one of their corresponding ends for movement toward or away from each other and ada'pted to em brace a rail of a window sash, means for securing said arms in their adjusted positions relative to each other, a bolt extending between and engaging said arms, a wedge ounted on the bolt between said arms, and an adjusting nut carried said bolt, said arm being movable toward each other upon rcttfion oi the nut on the bolt.

2. it wii TlOW lock comprising a pair oi" arms adapted to ,;e a rail of a window sash. each arm havino" one end thereoit extended in angular relation, corresponding;- e2 ds of said arms having registering opengs, tastening means disposed in said openfor holding the arms in various adj ustet positions, a bolt extencing between and engaged with said arms, a wedge member "Ilt(l by the bolt, and an adjustable plate combination with the upper and lower sashes of awindow, a bracket com sing a pair of ad ustably connected arms,

.;olt extending between and engaging said arms, said bolt being adapted to urge the ends of the arms n engagement with a porsignature.
